Caisleán Dúinlice [Doonlicka Castle] is rather
a small square building in full external preservation but gutted. It
stands on the isthmus of a little peninsula which runs into the sea
about two miles south west of Kilkee and eight from Dún Beg.
Nothing could be more wildly secure than the site of this edifice.
